Muda is the Japanese term for 'waste', 'uselessness', and 'futility', but is most commonly used to mean 'waste', and specifically within a business context. In business, actions that don't directly provide value to a business are defined as wasteful.

The original seven wastes (Muda) was developed by Taiichi Ohno, the Chief Engineer at Toyota, as part of the Toyota Production System (TPS). The seven wastes are Transportation, Inventory, Motion, Waiting, Overproduction, Overprocessing and Defects. They are often referred to by the acronym 'TIMWOOD'.

Muda, Mura, and Muri are Japanese terms that refer to the three broad categories of waste found in a business.

A yell, like "oi!" or "ayy!" or "hey!" or whatever. It gets used toward children or animals when they're doing something improper. You could translate it as "watch out" or "stop that!" depending on the situation.

Muda. Muda is a Japanese word meaning "futility; uselessness; idleness; superfluity; waste; wastage; wastefulness", and is a key concept in the Toyota Production System as one of the three types of variation.

A native speaker's definition of yare-yare

One native speaker says that it “expresses a mix of relief, mild dismissal, and mild annoyance without being too serious.” They elaborate by saying it indicates a “lack of enthusiasm” and almost never expresses intense emotions.

The Toyota Production System, and later on the concept of Lean, was developed around eliminating the three types of deviations that shows inefficient allocation of resources. The three types are Muda (waste), Mura (unevenness), and Muri (overburden).

For example, during the transportation of materials from one location to another, is there any movement that can be eliminated or reduced? Additionally, it's considered muda if the load of the vehicle used to transport these materials is under capacity. Another example is documentation.

Is Muda harmful or not?

It disrupts the workflow while not adding value for the facility, leads to longer lead times, and can result in damaged or defected products. Motion: This is not the motion of the product, but rather the unnecessary movements of workers that are wasteful or harmful.

The Muda of waiting is easily the most obvious form of waste in a Kanban process. It frequently appears in two forms. First, tasks are idle because team members can't handle all of the WIP. Secondly, tasks are queueing to enter the next process stage because there is not enough capacity to pull them through.

Someone might exhibit a behavior that is maladaptive, unjustifiable, disturbing, OR atypical, but unless the behavior meets all four of the criteria, it is not considered a psychological disorder. You can try to remember the four criteria by remembering the mnemonic device MUDA.

Ohno Taiichi (大野耐一, Ōno Taiichi, February 29, 1912 – May 28, 1990) was a Japanese industrial engineer and businessman. He is considered to be the father of the Toyota Production System, which inspired Lean Manufacturing in the U.S. He devised the seven wastes (or muda in Japanese) as part of this system.

To help focus efforts in this area, Lean practitioners developed a list of eight wastes which establish the most likely areas where waste will occur: defects, overproduction, transportation, non-value adding processing, motion, waiting, unused talent and inventory.

The only way to eliminate muda, mura, and muri is to load the truck with three tons (its rated capacity) and make two trips.

Ara ara (あら あら) is a Japanese expression that is mainly used by older females and means “My my”, “Oh dear”, or “Oh me, oh my”.

What does ARA mean Japanese?

“Ara” is an interjection and means “oh” or “ah.” So, if “ara” means oh, then the literal meaning of ara ara is “oh, oh.”But of course, with Japanese, it's less about literal translation and more so understanding the nuance of how the word is used.

Hora – ほら – This piece of slang means “Look!” or “See?” – If this Japanese colloquial is drawn out to “Horrraaaa….” It can also mean “I told you so….”

“Mada mada” is a Japanese slang phrase that means “not yet” or “not good enough” in English. However, in context, the phrase is most often said sarcastically in a deprecating way, meaning “pathetic.”

If you already watched or read JoJo's Bizzarre Adventure in Japanese, you would know the iconic phrase by Jotaro Kujo: “やれやれ” -pronounced “Yare Yare”. The phrase is trasnlated to intrepretations such as “well well”, “good grief” and “give me a break.” It is a common expression in Japan used to show disappointment.

Muri, which means 'unreasonable' in Japanese can also stand for overburden, unreasonableness or absurdity. The idea behind this term is that you should always avoid any 'Muri' work which will result in an unreasonable amount of waste. The waste can be in time, materials or effort.
